SPECIFICATION forming part of Letters Patent No. 778,016, dated December20, 1904.

Application filed March 26, 1904. Serial No. 200,080.

To all whom, it may concern:

Be it known that I, PATRICK DORANJL subject of the King of GreatBritain, and a resident of Bayonne, in the county of Hudson and State ofNew Jersey, have invented a new and Improved Heater,of which thefollowing is a full, clear, and exact description.

My invention relates to heaters, and is particularly designed for theheating of portions of the frame members of such structures as steelvessels and the like.

It has for its principal objects the provision of a convenient andeffective apparatus for this purpose; and it consists in the variousfeatures hereinafter described and particularly claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective View of one embodiment of my invention inplace upon a frame member, parts being broken away. Fig. 2 is anenlarged central vertical longitudinal section therethrough. Fig. 3 isatop plan view. Fig. 4: is a transverse section on the line t 4 of Fig.2, and Fig. 5 shows a top plan view of a casing-head having another formof opening than that illustrated in the previous figures.

1O designates a casing, preferably of cylindrical form and ofsheet-iron. It is shown as divided into two longitudinal sections in aplane extending through the axis of the cylinder, these sections beingconnected at one side by hinges 11, while at the opposite side isprovided a securing device consisting of 'a hasp 12, pivoted at the edgeof one of the sections, this hasp being movable to engage a staple l3,fixed to the adjacent edge of the other section.

At the upper and lower ends of the casing are heads 1& and 15,respectively, each of which is formed in two sections corresponding tothose of the casing, the line of division between them being a diameterof the cylinder. Each of these heads is provided with a substantiallycentral opening 16 of a suitable form to permit the passage through itof the member to be heated, this being shown in the first four figuresof the drawings as an angleiron A. Each of the openings lies adjacent tothe meeting-line between the head-sections so that its walls areincluded in both said sections, thus enabling the casing to be openedupon its hinges and then closed in place about the member to be heated.The heads are preferably removably secured in place, they being providedwith an annular flange 17 fitting within the casing, to which they maybe secured by screws 18 or the like. In the upper head is a feed-opening19, which maybe provided with a closure or cover 20, and also in thishead, here shown as in the other section, is an outlet-opening 21, towhich is secured a flange 22, serving to receive a flue-pipe 23. Eachhead-section may carry a supporting member 24, from which is shownextending a section of chain 25, by which the heater may be supportedfrom any part of the structure to which it is applied.

Near the lower portion of the casing is an inlet or draft opening 26,which may have operating over it a damper or adjustable closure 27,conveniently pivoted at 28. Extending along the length of the cylinderis a series of openings 29. These may have secured about them flanges30, into which fit plugs or closures 81. If desired, the lower head mayalso be provided with one of these openings. The cylinder-walls, thispreferably including the lower head, may be covered with aninsulating-lining 32 of asbestos, fire-clay, or the like.

In the use of my apparatus the casing is furnished at each end with ahead having an opening corresponding in form to the frame member whichit is desired to heat. Two forms are here illustrated, the first,previously described, being for an angle-iron, and that shown in Fig. 5being for such rectangular members as are commonly used for the stems ofvessels. The casing is now openedv and placed about the member which hasbeen bent or distorted or which for any other reason it may be desiredto heat. The casing is then looked together by the hasp and staple andsupported in the proper position by the chain extending from its upperhead over some convenient portion of the frame. The casing may now besupplied with fuel through the feed-door 19, this fuel being indicatedat Fin Fig. 1, and ignited through the inlet-opening. The draft is nowregulated by the adjustment of the damper, and upon the fuel attainingcombustion throughout the member will become heated, this being allowedto continue until the desired temperature is obtained. The hasp is nowdisengaged and the casing removed, when the frame member may bestraightened in the customary manner.

If desired, instead of supplying solid fuel to the interior of thecasing hydrocarbon-burners may be introduced through the openings 29 andtheir flames directed upon the frame member. This will effect theheating in a similar manner.

By the use of my invention metal members may be thus speedily heated atthe exact point desired while they are still assembled, and thelightness of the apparatus enables it to be readily moved from one.place to another and supported in its operative position Withoutdifliculty.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent 1. A heater comprising a casing having a head at eachend'and formed in longitudinal sections dividing both the casing andheads, said casing being provided with feed, inlet and outlet openingsand also with a series of openings extending along its length, andclosures for the feed and inlet openings and the series of openings.

2. A heater comprising a casing having a head at each end and formed inlongitudinal sections dividing both the casing and heads, said casingbeing provided with feed and outlet openings near its upper portion, aninletopening near its lower portion and a series of supply-openingsextending along its length, closures for the feed and supply openings,and an adjustable closure for the inlet-opening.

3. A heater comprising a casing provided with a feed and inlet openingand having a head at each end and formed in longitudinal sectionsdividing both the casing and heads, each head being provided with anopening the 7 walls of which are included in both sections,

and supporting means carried by the upper head-sections, the headcarrying the supporting means also having an outlet-opening.

4. A heater comprising a cylinder divided into two sections in a planeextending longitudinally through its axis, a removable flangedhead-section for each of the casingsections, and separate securing meansextending through the easing into the flanges.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

PATRICK DORAN.
